Tamil Nadu police on Tuesday beefed up security at central government offices and installations across the state after few pro-Tamil activists hurled petrol bombs at a post office building in Mylapore residential area in the wee hours of Tuesday.
Police have arrested four activists of Dravidar Viduthalai Kazhagam, a little known pro-Tamil fringe group in this connection. Five petrol bombs were hurled at Mylapore post office, located in one of the most ancient Brahmin colonies in south Chennai, two bombs at neighboring Madaveli colony post office.
The activists were wanting India to boycott CHOGM meet at Colombo and demanded the prime minister to abandon his visit to the Island nation that many Tamil groups hold responsible for the genocide of innocent Tamils in Sri Lanka during its decisive push against LTTE in 2009 and 2010.
Police said there were no casualties but wall of Mylapore post office was damaged slightly. An AC machine kept outside the premises was also damaged.
The bombs were hurled a little after midnight on Monday night and Tuesday morning.
The police on Tuesday has sent an alert of all the district SPs to beef up security at all central government offices and installations.
The Sri Lankan mission offices in Chennai too were given additional security cover, police said.
